Scenic Drive over the Hai Van Pass by Private Car: Choosing Pass or Tunnel and Handling Weather
The pass is about 21 km and the tunnel 6.28 km, so a scenic drive and a crossing on the way to Hue are two different choices. This guide helps you choose and lists what to check.

The Hai Van Pass is about 21 km long and about 500 m high, a natural boundary between Da Nang and Hue and between two climate zones (public travel sources). Hai Van Quan, the gate on the summit, was built in 1826 under Emperor Minh Mang at about 496 m. So a scenic drive over the pass is a choice of its own, different from simply crossing the range on the way to Hue.
This entry is the Da Nang to Lang Co route through the Hai Van Tunnel, used as a guide. The route price includes fuel, road tolls and parking; waiting time and extra stops are confirmed separately.
Pass or tunnel: two ways across the same range
The Hai Van Tunnel is 6.28 km long, opened in 2005 and cuts the crossing of the range to about 10–15 minutes, against nearly an hour on the old pass road (Da Nang city portal and Vietnam News Agency). A trip through the tunnel reaches Lang Co and Hue faster, while a scenic trip takes the pass road and adds stopping time. The rate table has a half-day Da Nang – Hai Van Pass – Da Nang programme of about 4 hours, which serves as a guide for a scenic trip of its own.
Stops to check in advance
Hai Van Quan is a historic site on an administrative boundary; check opening hours and the areas open to visitors as they stand on your day. From the pass you can look down on Lang Co Bay and Lap An Lagoon, but the view depends on cloud and wind. Stop only where it is permitted and there is safe parking.
Weather decides the plan
Because the pass divides two climate zones, weather on the two sides can differ. In rain, fog or strong wind, using the tunnel or changing stops is discussed for your date; the final decision follows actual conditions.
The Da Nang to Hue day tour guide covers how to divide time when you continue to Hue; the scenic programme is on the half-day Hai Van Pass summit tour page.
